finding the molecular radius?

If I know my protein is 5000 Daltons, with a density of 1.3 g/cubic cm, and am asked to calculate the molecular radius, how do I do this?

I am told to use the fluid properties of water at 20 degrees celcius, and to use the relationship between volume, density, and molecular weight.

I am not given any info on volume, so how can I relate these 3 propeties to solve for molecular radius?
